Polytetrafluoroethylene
Brand: Teflon® PTFE — Chemours, Fluon® — AGC Chemicals, Hostaflon® — Dyneon/3M, TECAFLON® PTFE — Ensinger
Standards: ISO 13000, ASTM D3308
PTFE (Polytetrafluoroethylene), best known as Teflon®, is the ultimate chemical-resistant engineering plastic. It withstands virtually all chemicals, has the lowest coefficient of friction of any solid material, and operates continuously from -200°C to +260°C. Inherently flame retardant (V-0). Used in chemical processing, pharmaceutical, semiconductor and food equipment. Note: PTFE has relatively low mechanical strength and high creep — use filled grades (carbon, glass, bronze) for load-bearing applications.
